What is a
fertilizer?
Orga fertilizers are substances containing
rie
derived from the remains or by-product of an
anism. Examples of
a
fertilizers are cottonseed meal, blood meal, fish emulsion,
manure
sewage sludge.
Orga fertilizers are naturally rich in nitrogen, phosphorus,
potassium, the three major
rie
needed in plant growth. Orga
fertilizers depend on
ro
anisms found in soil to break t
down
release the
rie
.
What is al fertilizer?
Ci
fertilizers are syntheti
ly produced plant
rie
from in
a
materials. Because they are artificially made, many
al fertilizers contain acids that can be harmful to the soil's population of
ro
anisms. In this aspect,
al fertilizers have the potential to stunt plant growth.
Ci
fertilizer vs.
a
fertilizer
Fertilizers are created to target soil rient deficiency, which is a prevalent problem among home garden owners. One distinct advantage
al fertilizers have over
a
fertilizers is the fact that they contain all three of the major
rie
(nitrogen, phosphorus,
potassium). Orga
fertilizers can only either have high content levels of one of these three or have all three
rie
in low levels.
For its part, a
fertilizers are a much
aper
cost-effective alternative to
al fertilizers. Any home gardener can create his own br
of
a
fertilizer by composting or mixing cow, sheep, or poultry manure with other
a
matters. C
i
fertilizers on the other h
will have to be bought from a gardening store or horticulturists.
A noted aspect of a
fertilizer is its slow-release capability. This slow release of
rie
in
a
fertilizers can be both beneficial
potentially harmful to pla
. Slow release of
rie
means that there is less risk of over-fertilization. However, this could also mean that if the need for immediate supply of
rie
arises,
a
fertilizers would not be able to provide the needed supply. In contrast,
al fertilizers can prove pla
with an immediate supply of
rie
when the situation
ls for it.
Several al fertilizers have high acid content. Acids in
al fertilizers, like sulfuric acid
hydrochloric acid, lead to high soil acidity which would in turn result in the destruction of nitrogen-fixing bacteria, the
ro
anism that plays a key role in supplying a growing plant's nitrogen needs.
Pla certainly do not recognize the difference between
a
fertilizers
al fertilizers. Their tiny root hairs will absorb those
roscopic
rie
, regardless of where they come from or how they were manufactured. But even so, with today's growing environmental concerns, some people debate over the wisdom of using
al fertilizers as a
rient source.
